That sounds like a kernel, kvm or dnsmasq issue, rather than OpenStack itself. I think Quantal is on the 3.5 kernel, and I assume OpenStack is working there.. Maybe give it's dnsmasq package a go first as it's probably the easiest thing to check... Ubuntu also have some 3.5 packages for Precise, although they are test packages.. http://packages.qa.ubuntu.com/qatracker/milestones/223/builds Thanks, Kiall On Aug 9, 2012 8:14 AM, "Alessandro Tagliapietra" < tagliapietra.alessandro at gmail.com> wrote: > Hello guys, > > i've just installed kernel 3.4 from Ubuntu kernel PPA archive and after > this upgrade VM aren't able to get the DHCP address but with tcpdump i see > the request and offer on the network. > Someone else experienced this?
